What does the price depend on?

The capacity (tailored to the room), the number of indoor units, the distance between the indoor and outdoor unit, and any additional electrical work determine the price. We will advise you on the best setup without obligation.

Because a modern air conditioner also heats efficiently, you earn back a portion of your heating costs during the shoulder seasons.
